Doors are available through millwork shops, door manufacturers, lumberyards and home-improvement centers. Most manufactured doors are made by a handful of large companies; Premdor and Jeld-Wen, for example, own several smaller or regional door makers that each construct a particular type of door. These companies, in turn, ship to local distributors and dealers.

Hinged, or swinging, doors are the most common types of door because they are appropriate for practically every interior and exterior door application. This door type is typically used in front entries, as porch doors and doors from garages and basements, as well as common interior doors. While being the simplest and most traditional door design, the hinged door is multipurpose and durable, and still brings beauty and elegance to your home.

A door design contributes much to the overall scheme of a room and, indeed, an entire home.

When it's time to decorate your home, whether it's for a brand new home or a remodeling project, one thing that's often overlooked is the style of your interior doors. The style of the door that you choose can make a subtle, definitive difference throughout your home. Unfortunately, the majority of today's new homes feature interior doors that are bland, hollow-core with plain brass knobs. They offer no character at all. You will be amazed at what a difference changing such a subtle design accent can make throughout your home.

An exterior door can include any entry door such as the front door or back door. Generally, this door leads from the outside into your home. Exterior doors are heavy duty and should be weatherproof and painted or stained with a quality product to help it last. They also usually have a sturdy lock system to prevent intruders from entering into the home.
